<h4><a name = "tag_001_009_169">&nbsp;</a>NAME</h4><blockquote>
mvderwin - define window coordinate transformation
</blockquote><h4><a name = "tag_001_009_170">&nbsp;</a>SYNOPSIS</h4><blockquote>
<pre><code>

#include &lt;<a href="curses.h.html">curses.h</a>&gt;

int mvderwin(WINDOW *<i>win</i>, int <i>par_y</i>, int <i>par_x</i>);
</code>
</pre>
</blockquote><h4><a name = "tag_001_009_171">&nbsp;</a>DESCRIPTION</h4><blockquote>
The
<i>mvderwin()</i>
function specifies a mapping of characters.  The function identifies
a mapped area of the parent of the specified window, whose size is the same as
the size of the specified window and whose origin is
at (<i>par_y</i>, <i>par_x</i>) of the parent window.
<ul>
<p>
<li>
During any refresh of the specified window, the characters displayed in that
window's display area of the terminal are taken from the mapped area.
<p>
<li>
Any references to characters in the specified window obtain or modify
characters in the mapped area.
<p>
</ul>
<p>
That is,
<i>mvderwin()</i>
defines a coordinate transformation from each position in the mapped area to a
corresponding position (same <i>y</i>, <i>x</i> offset from the origin) in
the specified window.
</blockquote><h4><a name = "tag_001_009_172">&nbsp;</a>RETURN VALUE</h4><blockquote>
Upon successful completion,
<i>mvderwin()</i>
returns OK.  Otherwise, it returns ERR.
</blockquote><h4><a name = "tag_001_009_173">&nbsp;</a>ERRORS</h4><blockquote>
No errors are defined.
